It's not your swing.
It's your hips.
You've changed grips, changed drills, maybe changed coaches. Something clicks for a while, then the same fault creeps back in. Here is the physical limitation most golfers never get properly screened for, and why the fix starts nowhere near a golf club.
A confession.For a long time, I screened golfers for hip mobility and left it there.
If the numbers looked reasonable on the table, I moved on to the swing itself. Grip, stance, tempo, all the usual places a coach and I would go looking for the fault. Some golfers responded well to the mobility work I gave them. Others did every drill I set and the same pattern kept turning up in their swing.
I told myself they were not doing the homework.
They were doing the homework. The problem was what I was measuring, not their effort.
This is not an argument against mobility work. It has a real place. But mobility on a table and mobility inside a fast, loaded, rotational movement are two different questions, and for a long time I only tested the first one. Once I started testing the second, it changed how I screen every golfer who walks in.
If you have done the stretches, done the drills, and the same fault keeps showing up under pressure, you are probably in that group.
The golfer who passed every mobility test in the room
Mark came in on a Thursday after his lesson, a familiar story. Mid-forties, plays off a mid-teens handicap, out most weekends. His hip internal rotation measured fine lying on the table, both sides. His coach had him on a stretching routine for a swing fault that would not go away: standing up out of the shot on the downswing, losing posture right through impact.
He had done that stretching routine for four months.
That client line below is the whole story.
My hips feel fine when we test them lying down. They just don't feel fine at the top of my backswing.
Fine at rest and available under load are not the same question. Something else was happening the moment speed and rotation entered the picture.
What is actually driving the fault
Here is what I used to miss, and what a lot of golf fitness screening still misses.
Hip range on a table tells you what is available. It does not tell you what the body will actually use under load.
Internal rotation at the hip is not just a joint mobility number. In the swing, that range has to be accessed while the pelvis, rib cage and torso are all coordinating at speed, under load, while the nervous system manages balance and force at the same time. A hip can measure well on the table and still not access half of that range inside a real backswing, because the body has never been trained to load into that range while everything else is moving.
The rib cage plays a bigger part in this than most golfers expect. Breathing mechanics set the resting position of the rib cage and the rib cage's position changes the starting geometry of the pelvis and hips before the swing even begins. A rib cage that sits flared and lifted, the pattern common in a shallow, chest-dominant breather, pulls the pelvis out of a position where the hip can rotate freely underneath it. It is like trying to turn a door that is slightly off its hinges. The hinge might be fine. The frame around it is not.
Why strength and coordination matter as much as range
Mobility work restores available range. It does not teach the body to use that range under speed and load, and it does not build the pelvic control needed to keep the base stable while the hip moves. Movement screening systems such as those used by the Titleist Performance Institute (TPI), and the position-first training principles used in Postural Restoration Institute (PRI) informed programs, both point at the same gap: range without the strength and coordination to use it rarely shows up in the swing.
Mark's hip mobility was never the limitation. His ability to load, rotate and stabilise through that range, at swing speed, was.
Mobility work changes what your hip can do on a table. It does not change what your body will use in the swing.
What to do differently
The most useful place to start is not another hip stretch. It is loading the rotation you already have.
Once a golfer's baseline range is confirmed and any real restriction is ruled out, the work shifts from stretching to loading: building rotational strength through the hip while the pelvis stays controlled, retraining the breath and rib cage so the pelvis has a stable base to rotate underneath, then putting that new capacity into the actual movement pattern of the swing, at speed.
- 1
Strength replaces stretch as the driver. Training the hip to control and produce force through internal rotation matters more than adding a few more degrees of passive range.
- 2
The rib cage and pelvis get retrained together. Breathing work restores a resting position that lets the pelvis and hip rotate freely underneath it, before any swing-specific work begins.
- 3
The new range gets built into the swing itself. Range and strength trained in the gym only transfer if they get practised inside a real, loaded rotational pattern, not just isolated drills.
Mark's second block of sessions barely touched a stretch. Rotational loading, breathing and rib cage work, then transferring it into his setup and takeaway on the range.
He noticed it before I did.
"I don't feel like I'm holding myself up out of the shot anymore," he said.
Nobody stretched anything to get there.

A sixty-second hip rotation check at home
Stand side-on to a wall or bench, trail-side hip about a hand's width away. Keeping your trail foot flat, slowly rotate your pelvis toward the wall as if starting your backswing, then rotate back to a neutral setup position. Use the guide below to pace five slow rotations, spending a moment loaded at the end of each turn before you release it.
Notice which side runs out of rotation first, and whether you feel it more in the hip or the lower back.
This is a loading check, not a diagnosis. But it is a signal worth paying attention to.
Self-check · 90 seconds
Is your fault coming from range or from load?
Six questions. Honest answers. About ninety seconds. This will not diagnose you, but it will give you a useful starting point.
1When your hips get checked for mobility, how does your range usually come back?
2Does your swing fault show up more under pressure or at higher swing speed?
3After a warm-up or a few practice swings, does the fault improve?
4Do you find yourself sliding or swaying sideways instead of rotating in the backswing?
5When you take a full, relaxed breath in, what moves first?
6Have you done hip mobility drills consistently for more than a month without the fault changing?
This self-check is educational and not a clinical assessment. For a proper evaluation of your movement and swing mechanics, a one-on-one assessment with an exercise physiologist is the most useful next step.
Questions I get asked
No, and I want to be direct about that. Mobility work has a real place, especially when a genuine restriction shows up on assessment. The limitation is treating every swing fault as a flexibility problem. If your range checks out reasonably well and the fault still shows up under speed, more stretching is unlikely to be the answer. For some golfers, mobility work is exactly right. For others, it is solving the wrong problem.
The rib cage and pelvis are part of the same pressure system through the trunk. How you breathe sets the resting position of your rib cage, and that position changes the starting geometry your pelvis and hips work from before you even start your swing. Retrain the breathing and rib cage position, and the hip often has more usable rotation available underneath it, without a single hip stretch.
TPI screening is a genuinely useful tool for identifying where a physical limitation might sit. What it does not always capture on its own is whether range that tests fine on a table actually holds up once you load it, rotate it and add speed. As a TPI Certified Professional, I use the screen as a starting point, then test how that range performs under load, which is often where the real answer is.
Honestly, it varies. Some golfers feel a difference in how a rotation loads within a single session, the way Mark did. Building genuine rotational strength and a new resting breathing pattern that holds up under swing speed takes consistent work over weeks to months. I would rather be upfront about that than give you a timeline that does not fit your situation.
No. Most of the golfers I see are not injured. They are dealing with a performance fault, lost distance, or lower-back tightness that shows up after a round rather than a diagnosed injury. If you do have pain, particularly anything sharp or persistent, that changes the starting point and is worth having assessed properly first. See our Golf Performance page for more on how we approach both.
